To all whom it may concern:

Be it known that we, ALBERT GVLUDLUM and ARTHUR Lowr, citizens of the United States, residing at New York, in the county of New York and State of `New York, and Newark, in the county of Essex and State of New Jersey, respectively, have invented certain new and useful Improvements in Apparatus for Setting Bring-Bushings, of which the following is a full, clear, and eXact speciication. i I

This invention relates to apparatus for setting bushings in bung holes of barrels and the like. The object of the invention is to provide a hand operated device comprising a novel form of bushing setter with means for holding it in operative relation `to the barrel and bushing.

it is the object `of the present invention to provide a simple, inexpensive and easily portable apparatus, which will be readily positioned for operation and which will turn over the flange on the bushing with an economy of attention and effort not attainable Vby prior devices. With this end in view, the bushing setter of this invention comprises an outer sleeve portion stationary on the bushing and holding it against turning moments and an inner relatively rotatable spindle carrying fianging rollers at the ends of pivoted flanging arms, which automatically position the rollers relatively to the work. f This automatic control of the-operation of the rollers is particularly useful where the setting operation is carried on out of sight of the operator as is usually the case in setting bung bushings.

A further object of the invention is to support the setter with relation to the barrel and to fasten it in place on the bushing.

For this purpose a. stand is provided for the barrel and the setter is fastened to the stand and held down on the bushingby link members connecting the setter to the stand and adjustable in vtension to hold the parts rigidly together. By this means the barrel is held in place on the sta-nd and the outer sleeve of the setter is pressed against the bushing and holds it from rotating in the barrel.

By these means the setter and barrel are easily positioned and are held in proper operative relation by the fastening means so` that the operator can devote his entire attention vand effort to the operating of the Hanging spindle. ter .can be lifted up out of the way until again required.

In the accompanying drawings showing Y -with the out-er sleeve 1 and carries a central'- spindle sleeve 3 rotating and moving longitudinally in the outer sleeve 1. Between the spindle 3 and the sleeve 2 is a bearing a taking up the thrust between collar 5 on the spindle 3 and the cup 9 at the upper end of sleeve 2. The cup 9 of sleeve 2 carries a hand wheel 6, whereby the sleeve 2 is rotated with relation to the sleeve 1 and moved longitudinally to vraise or lower spindley 3. Spindle 3 is independently rotated by hand wheel 7 fastened to its upper end.

The lower endy of the spindle 3 is slotted as shown at 8 and within the slot are positioned arms 11 on pivot '10 and carryingV lianging rollers 12. Arms 11 are normally collapsed within the slot 8 by springs 13 bearing outwardly against the lower ends of the arms. Sliding centrally through spindle sleeve`3 is the rod 15 carrying a wedge 16 at its lower end which actsk when the rod is pressed downwardly to spread the Hangingarms into operative position. To the upper end of rod 15 1s fastened a rope 18 pass'- ing over pulleys 19 and counterwelghted at 20 to sustain the weight of the setter. The' rod 15 carries a collar 17 at its lower end engaging the up-per end of slot 8 and holding the rod 'from withdrawal.

In the normal operation of the device the rod 15 is held in itsk uppermost position by counterweight 2O leaving the setter and TWhen completed, the set- Hanging arms 11 held collapsed within slot c 8 by springs 13.` The operator drives the bushing B into the vhole in barrel A, and then lowers the setter into the position shown in Fig. 1 with its spindle sleeve3 extending within the bushing. The sleeve 2, has prel viously been moved to lower the spindle 3 sufficiently so that the Hanging rollers will.

take a position below the lower bushing edges as shown in Fig. l when spread by the downward movement of Wedge 16 on central rod l5. lllhen so spread, sleeve 2 is rotated by hand Wheel 6 to raise the flanging rollers into tight contact with the bushing. Central rod l5 is released and sleeve 3 is rotated by hand Wheel 7 and raised gradually by rotation of sleeve by hand Wheel o to flange and turn over the bushing B against the barrel. As the flanging operation progresses the Hanging arms ll more outwardly around their pivot so that'the flanging rollers automatically follow the bead they are forming and increase their angle thrust as the danging operation increases. This prevents longitudinal compression of the bushing, or upsetting.

ln operating the spindle o the relative amounts of rotating and raising movements can be controlled by the relative amount of rotation of hand Wheels 6 and 7. ln practice, hand Wheel G is usually rotated slightly to produce a 'slight bend in the bushing flange and then hand Wheel T is rotated to carry this bend completely around the bushing,` these operations being repeated succes-V sively until the flange is finally formed and spun up onto the barrel rotation of the hand Wheel T. T he operator can tell by the resistance offered to the turning of hand Wheel 6 when the flange is fully set. By reverse turning movement of hand Wheel (l1 spindle 3 is lowered and its flanging arms carried out of engagement With the set bushing and collapsed Within slot 8 by spring 13 so that the operator has only to lift the setter to remore it from the barrel.

ln order to hold the setter in place on the barrel, a stand 27 is provide-d comprising end pieces shaped to receive the barrel and connecting side pieces. Chains 2G and 28 areV fastenedto side vpieces of the frame and extend upward around the barrel and are adjustably fastened to the outer sleeve l. The chain 26 has one of its links engaged by the lug 25 of pawl 2 adjustable in slot 22 of the arm 2l extending from sleeve l. The bottom of slot is serrated as shown at l2 and is engaged by the point lr-3 of panfl 2e. rl`he upper part of slot 2'2- is undercut to form the overhanging ridges 23 engaging the body of panl 24 When tipped by the tension of chain 26 and holding said pawl Yin contact with serrations rlhe chain 2S has one of its linlis engaged by collars formed .by a slot in 1web 3i extending across the periphery, winding drum 3l on shaft BO rotating in bracket 29 on sleeve l. Fastened to shaft 30 is the ratchet `v\'heel 33 carrying the handle 35 and engaged by dog 34.

rlhe rough adjustment of the chain length provided by dog Q4 serves to center the setter on the barrel in approximately vertical operation. ln the operation of the holding means the barrel is positioned on the stand 27, the setter is lowered into position on the bushing, the proper linlr of chain 2G is placed over lug of paal' i4 which is adjusted in proper position Within the slot 22 to approximately center the setter in yertical position. Chain 2S is then caught in slot of capstan 3l and the handle 35 moved down clockwise, as seen in lfig'. l, to draw the chains taut, dog 3e holding the handle 35 in its final position by engagement With ratchet 33 In this Way the barrel is held on its stand and the fixed sleeve of the setter is pressed into tight engagement With the bushing B holding said bushing against rotation'during the Hanging operation. llith the setter so held in proper position the operator vis free to devote his entire attention to the proper manipulation of the flanging spindle as above described and he may use both hands to turn Wheels G and T simultaneously or in quick alternation until the flanging and setting operation is comple-te.

rilhe release of the holding means is easily accomplished by raising dog 34 and removing the chains 26 and 28 from engagement with lug 25 and capstan 30, respectively. lllhen so released, the setter is free to be lifted from the bushing and the barrel fr can be taken from the stand.

lt Will thus be seen that there is provided a simple, easily portable apparatus` which will hold the setter, barrel and bushing in proper relation. The setter prevents rotation of the bushing in the barrel and the fianging means is constructed Yto reach into the barrel and set the bushing with a minimum of attention on the part of the operator. The flanging rollers are easily positioned with relation to the bushing and When so positioned operate to gradually turn over the setting flange. rEhe relative resistances offered to the turning of Wheels 6 and 7 inform the operator as to the character and extent of the Hanging operation so that the relative movements of advance and rotationl be properly proportioned for each bush-V ing. A

t is apparent that other means may be'v used to hold the setter in place on the barrer or that special holding means may bej dispensed With altogether and We do not Wish to confine the invention to the specilic embodiments above described, but intend to include such modifications thereof as fall Within the scope of the appended claims.
